If a mutation in the DNA of a globular enzyme changed all of the leucine amino acids to isoleucine, predict how the relative position of the amino acid in the tertiary structure of the protein would be affected when the protein is placed in an aqueous solution. If the leucine amino acids were found within the active site of the enzyme, discuss the effect this change is likely to have on enzymatic function.

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
